To all whom. it may concern.-

Beit known that 1, WILLIAM C. REILLY, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented or discovered new and useful Improvements in 'Ma chines for Recessing Couplings, of which the following slot connection, one section containin the slot 16 while the other contains the pin 17 which is adjustable along said slot and secured in any selected adjustment by a nut on the pin clamping the two sections together. The rack-bar 15 is supported on the rest 15 seated on the spring 15 in a socket in the bracket 15. The worm-wheel 12 is driven by the worm 18 on the My invention relates to machines for recessing the shaft 19 provided with the pulleys 20, connected by the ends of pipe-couplings, and its object is to provide a machine which will accurately center the couplings relative to their threaded interiors while the ends thereof are being recessed. Preferably both ends of each coupling are recessed simultaneously by cutters rotating in opposite directions, whereby the couplings can be held in their chucks with the expenditure of less power.

Referring -to the drawings ries the spur-gear 24.

The boring mandrels 29 are supported, in the bearings 25011 the mandrel-saddles 5 andG and are provided with 1 the spur-gears 26, meshing with the barrel-pinions 27, along which they slide as the mandrelsaddles move along the guides. The pinions 27-are driven through any desired-gearing by the motor 28, which through intermediate connections drives the gear-wheel 24. The boring mandrels 29 are each provided with the cutterchuck 30 'at their opposing ends, and also with a centering device for centering the coupling true with the thread, which'has been cut therein. This device consists of a spindle or rod 31 housed in the mandrel in such a manner that it can slide endwise and. is prevented from turning by having its outer end square and housed in the bracket 32 carried by the mandrel-saddle and having a square opening to fit the square end of the spindle. 1

Each spindle has its inner end provided with the centering disk 33 which is of the proper diameter to fit. the inside of the coupling at such a distance from the end of the coupling 34 that it will be out of the way of the recessing cutter 35, when the proper length of the which accompany this of my invention; Fig. 2, a front elevation; Fig. 3, an end elevation looking toward the left on Fig. 2 Fig. 4, a rear elevation of the chuck for the coupling; Fig. Fig. 6, a detail, showing partly in section the cutter chucks in working position with the coupling; Fig. 7, a detail, showing in section the worm wheel for feeding the cutter chucks and the clutch therefor; Fig. 8, a detail partly in section, showing the clutch releasing mechanism; Fig. 9, a plan of the-shifting bar for operating the said clutch; Fig. 10, an end view of one of the cutter holders; and Fig. 11, a side view of the same.

On the drawings, 1 is the leg or base, upon which the gear table 2 rests. The table 2 supports along its front the guide 3,Zwhich isan open frame, having the v lead-screw 4, journaled in its ends, the screw having 31 is provided with 7 one end with right-hand threads and the other end, the bracket 32 and the collar38 adjustable on the spinwith left hand threads. The two mandrel-saddles 5 die by the set-screw 39. The oflice of the spring and and 6 are slidable on the front of the guide 3, saddles 5 the collar is to prevent the damaging of the threads in and '6 having secured thereto the nuts 7 and 8, respecthe coupling after it has been centered by the disk 33 tively, the former nutcooperating with the screw and while the boring mandrel is moving toward the threads on the left-hand end of the screw 4 and the coupling. The centering disks remain stationary after latter nut, with the threads on the other end of the engaging the inwardly tapering interior of the coupling 4 is operated by the shaft 9 while the boring mandrels move relatively to the disks. through the bevel-gearing 10. The shaft has keyed Owing to the tapering Opening the disks could not move thereto the friction dis t 11, which cooperates with the toward each other after engaging the threads Without face of the Worm-wheel 12,' loose on the shaft 9 and damaging them. The springs 37 are compressed bythe which is forced against the disk 11 by the hand-operbrackets 3211s they travel toward the coupling. When ated nut 13 working on the said shaft and against the the boring mandrels are withdrawn, the springs keep worm-wheel. The nut 13 is provided with the circle the centering spindles toward the finished coupling 34 of teeth 14, which point in the direction of the rotation far enough to permit the centering disks to enter a of the nut when turned to clamp the worm-wheel and new coupling far enough in advance of the cutters 35 to the friction disk together, the teeth meshing with center the new coupling before the cutters engage it. similarly-shaped teeth of the rack bar 15, carried by The coupling is clamped tight in the chuck '40 by the mandrel-saddle 5. The bar 15 is made of two means of the radially adjusted dogs 41, the chuck being sections, adjustably secured together by the pin and 1 in two hinged sections secured together by the handbelt 21: to the pulleys 22 on the shaft 23, which also carnut 42. The chuck is corded. by the chuck-saddle 4.2, slidablc on the guide 3 between the mandrel-saddles 5 and 6, by means of the rack 43 thereon and the pi voted rack 44 moshing therewith. The rack 44 is pivoted oi 15 on the iron't of the leg 1 and has the lateral lugs 46, adapter ior engagement by the operators feel; to move the ohmic-saddle to the right or the left after the coupling has been clamped in the chuck m order that, the coupling may be centered between the cutters whereby the iotter may commence to Work on the ends of the coupling simultaneously.

The chuck rests on the flat sieel spring 4730 that it can be raised 01 lowered when centering on untrue coupling. The chuck also has lateral movement on the pin 48 for the same purpose; I

The chucks which liolcl'the couplings and the con tering disks 33 roost be changed for each size of coup ling. The cutter-chucks will also hove to be changed to suit the different sizes 0; couplings.
